About Renewell Water
At Renewell Water, we believe better health starts with what you drink. Founded by Simon Newell in 2002, our journey began with a personal search for better health that led to the discovery of Reverse Osmosis — a powerful filtration process that transforms ordinary tap water into pure H₂O. The results were life-changing and inspired a mission to help others experience the same benefits.

Better Water
Our advanced filtration system uses a series of powerful layers to remove impurities, bacteria, odours, and heavy metals—ensuring every drop is crisp, clean, and safe.
Better Future
Water that is good for you and great for the Planet. A single year using a Reverse Osmosis filter can replace up to 1,000 plastic water bottled, saving the environment from 90 kg of CO₂ emissions in the process.
Better Value
To reach your daily water intake of 1.5 litres, you need about 500 litres per year. Compared to buying bottled water, you can save up to €300 per year – as a single household with our drinking water filters.
